4.1 Message frame configuration
The MODBUS message is the configuration like a list shown below.
Due to the MODBUS RTU mode, the message is configured of all the binary data.

4.2 Slave address: Detector No.
Program the slave address (the detection number) in 1 to 9 ranges previously by using front key.
The master usually communicates it to 1 slave.
All the connected devices are received the message from the master in common.
However, the only slave in accord with the slave address answers the message.
4.3 Function code
The function code is the implementation command code to a slave (detector).
Each data is the next classification approximately.
(1) Analog input data Measured data, Status etc.
(2) Analog setting value Various kinds setting information such as the detector, calibration curve.
(3) Digital setting value Smoothing/Real switching, Preset output ON/OFF etc.

4. MODBUS protocol-Message
Programming to the slave address (the detector number) of IRMA series.
·Press SEL key and ENT key for more than 2 seconds simultaneously and move to
[Setting operation conditions] mode screen.
·By pressing the SEL key several times, program it at the item of [Detector
number (Hn)].
(Refer to [6.4 Setting operation conditions] in the separate manual “IRMA series
infrared multiple-constituents analyzer detector unit Model for IRMA ”.
Details, refer to [5.3.4 Reference table of an analogue setting value] and [5.4.4
Reference table of a digital setting value].
